Participants split into two lines so that each person faces a partner. The facilitator then comes up with a topic everyone should discuss and put their opinions on it (e.g. ”Is the Earth flat?”). Line one has to say “Yes” in as many different ways as possible, and line two has to try to change their partner’s minds by saying “No” as convincingly as possible. Give both lines a chance to say both “Yes” and “No”.
Discuss how people felt. How did it feel to say “Yes” or “No”? Was it easier to say one than another?
